摘要:
The present invention is directed to a pneumatic tire (10) with a built-in sealant layer. The tire (10) comprises an outer circumferential rubber tread (14), a carcass (16), and an innerliner layer (22) disposed radially inwardly from the carcass (16), wherein the tire comprises a built-in sealant layer (20, 20A, 21) comprising a polyurethane based sealant material, wherein the built-in sealant layer (20, 20A, 21) is positioned between the carcass (16) and the innerliner layer (22), and wherein the built-in sealant layer (20, 20A, 21) is a multilayered composite layer, the multilayered composite layer comprising a first polyurethane layer (21), a second polyurethane layer (21 A) and an intermediate layer (20A) positioned between the first and second polyurethane layer (21, 21A). The intermediate layer (20A) comprises at least one of:
(A) a non-woven microfiber layer containing polyurethane,
(B) particulate pigment,
(C) discrete fibers,
(D) cured rubber particles, and
(E) a woven microfiber layer containing polyurethane.
Also, a method of manufacturing a non-woven microfiber layer containing polyurethane using as intermediate layer (20A) is disclosed.
